Say we have a population, with Ne = 100, containing two alleles, A1 and A2 at frequencies 0.6 and 0.4, respectively. We leave th

is population alone for 10000 generations (keeping its size constant), then come back to find that the allele frequencies are still 0.6 and 0.4.
a) Explain why this would be evidence that selection is acting in this population.


b) Which genotype would you expect to have the highest fitness in this case? Explain.

Answer:

a. It is found that even after 10000 generations, the allele frequency is still the same, that is, 0.6 and 0.4. This shows random mating population. None of the other factors like emigration, immigration, mutation, and others are operating. On the basis of Hardy-Weinberg law, if a population stays in random mating with no factors operating, in such situation, allele frequency will stay same from generation to generation. That is why in the given case, the allele frequency is still similar.  

b. In a random mating population, all the genotypes are identically fit. In such populations, the phenomenon of natural selection does not take place.

In the human brain, a great deal of synaptic pruning occurs in early childhood. This pruning appears to be:_______.
Alex

Answer: D. An adaptive process that allows children to deal more efficiently with their environment.

Explanation:

Synaptic pruning is a natural process between early childhood and adulthood which occurs in the brain. The brain removes the extra synapses during synaptic pruning. Synapses are brain structures that allow the neurons to transmit to another neuron an electrical or chemical signal.  

Synaptic pruning is thought to help the brain transition from adolescence, when it can quickly learn and make new connections, to adulthood, when it is much more stable in its structure, but can concentrate on a single question for longer and conduct more complex thinking processes. Synaptic pruning make brain more adaptive to the external environment in early ages.

Hence, the correct option is D. An adaptive process that allows children to deal more efficiently with their environment.

On the northern hemisphere the north is to the left, the Sun rises in the east (far arrow), culminates in the south (to the right) while moving to the right and sets in the west (near arrow). Both rise and set positions are displaced towards the north in summer, and towards the south for the winter track.
